I think you need to write the answer in a paper with full solution and take a photo of it and upload the image.
For this case we have the following equation:
h (t) = - 12t2 + 36t
When the object hits the ground we have:
- 12t2 + 36t = 0
We look for the roots of the polynomial:
t1 = 0
t2 = 3
Therefore, the time it takes the object to hit the ground is:
t = 3 s
Answer:
the time when the object hits the ground is:
t = 3 s
First you would subtract Minas friends mile time from Minas mile time.
11.02-9.4
Mina is 1.62 minutes faster than her friend
